Blender is really cool in that you can mix your modes of editing between projections of that video in 3D space, 2D-based compositing, and 2D-based mixing in the VSE, all at the same time. An über-cool idea is to use your video to texture something - a plane, or a sphere commonly, and then film that texture using the camera (orthographic or lens-based) to get all sort of very cool distortion effects. Whether you're new to the Blender Foundation's popular 3D modeling program or a seasoned graphic artist just interested in better acquainting yourself with the application, you're sure to be well served by this free video tutorial.
